In 2010, a PhD candidate at the London Royal College of Art designed a scale model of a steel roller coaster that would kill anyone who rode it. The candidate, who used to work at an amusement park, said the end goal would be to "take lives with elegance and euphoria." He also suggested it could be used for execution.

Going into outer space without a spacesuit is insanely dangerous, and can be damaging to one's physical and mental health. Due to the lack of pressure and oxygen in space, the human body could become unconscious and die, lose an incredible amount of body heat, or their bones could deteriorate.

President John F. Kennedy was assassinated on Nov. 22, 1963, in Texas, and his autopsy was performed that evening in Maryland. Physicians found he was hit by two bullets, one from above and one from behind, one of which made the right side of his skull explode.

She was tortured and burned to death by four girls in Indiana in 1992 because one girl claimed Shanda stole her girlfriend. Shanda was only 12 years old, and her killers, who were between 15 and 17 years old, were tried as adults. Today, most of them are out of prison.

The South end of the Chicago River used to literally bubble up as a result of meatpackers dumping blood and excrement into the water in the early 1900s. The water is still heavily contaminated and is slowly being cleaned up, but knowing its history of being filled with blood is terrifying.

He was a distinguished herpetologist, meaning he studied amphibians and reptiles, and was one of the world's top experts in the field. In 1957, he was bitten by a boomslang snake, and began writing down every symptom he experienced. Hours before he died, he was offered medical help — but denied it because he didn't want to upset the symptoms.

This ghost ship has so many legends and tragedies attached to it, from rumors that it was used to smuggle potassium cyanide and nitroglycerin, to stories about a horrible accident in the 1940s that killed an entire crew. But despite all these tales, the creepiest thing about the SS Ourang Medan is that there's NO ACTUAL PROOF IT EVER EXISTED.

This controversial type of therapy is used to "treat" attachment disorders. In 2000, 10-year-old Candace Newmaker was treated with a method called "rebirthing." She was wrapped in flannels to represent a womb, was sat on, and told to free herself. She screamed, vomited, and died under the sheets. Similar deaths have been reported as a result of this therapy.

Numbers stations are radio stations that supposedly send messages to intelligence officers using codes, numbers, and synthesized voices. From the '70s to 2008, the Lincolnshire Poacher station transmitted from a Mediterranean island, and was believed to have been operated by the British Secret Intelligence Service. You can listen to a bone-chilling example of its broadcasts here.

This horrifying method of execution is believed to have existed in ancient Persia. It consisted of trapping a person inside two hollowed-out boats, covering and feeding them with honey and milk, and leaving them to die while rats ate them to death. Scaphism is referred to in fictional books, but there's little evidence to prove it's ever been used in real life.

The High Frequency Active Auroral Research Program (HAARP) was established in 1993 and funded by the US Air Force, Navy, and a few other groups. Its purpose is to "enhance radio communications and surveillance," but conspiracy theorists argue it has the ability to trigger earthquakes, flip the Earth's magnetic poles, or even control people's minds.

The SCP Foundation is a fictional organization created by a group of writers online. In this imagined universe, there are objects, individuals, paranormal creatures, and even places that "violate natural law," also known as SCPs. The creepy thing about it is how real all of their "collected data" seems, as a result of the fantastic writing abilities of this online community.

Kremers, 21, and Froon, 22, went for a hike in Panama in 2014 and disappeared. Their camera was found weeks later, with pictures that'd been taken after they'd gone missing. Two months later, bones were found throughout a nearby forest that belonged to both women — but how they died is still undetermined.

Spiritualists believe that the dead are able to communicate with living beings, and that spirits can provide useful ethical and moral advice. Spiritualism was at its peak in 1897, but soon its popularity dwindled due to accusations of fraud by mediums.

Rosalia was almost two years old when she died of pneumonia in Italy in 1920. Her death was made even creepier when her heartbroken dad got her body embalmed so she'd be perfectly preserved forever. It's currently on display in the Capuchin catacombs of Palermo.

It seems impossible, but entire planes, some filled with people, have gone completely missing with little to no debris or bodies found. Starting in 1856 to the present day, a horrifying reality has been proven: Sometimes people go missing and may never be found.

A man checked into a motel in Washington in 2001 using the fake name Lyle Stevik. In that room, he committed suicide by hanging, and his body has yet to be identified. The name he chose refers to a character from a Joyce Carol Oates book who also tried to commit suicide.

In 1998, two separate groups of scientists determined that the universe has been expanding at an accelerated rate, starting about 5 billion years ago. This means a few things: That dark energy could someday dominate the entire universe, that the universe could become too cold to sustain life...basically, something bad could happen to our universe someday, and we may not even survive to see it.
